I have often wondered whether it's possible to use automatic car washes at sub-zero (Celsius) freezing temperatures. I believe the water used in the car wash is heated in these cold temperatures. So it's not like the car would be washed with ice!
But is there a risk that the water freezes someplace it shouldn't, leading to a frozen door, non-working brakes or something similar?
Is there a limit for the temperature where car wash is still possible? I mean, -5 degrees Celsius probably is fine, but is -30 degrees Celsius? I know modern fluids (motor oil, coolant, washer fluid) in cars work just fine even at -30 degrees Celsius.
